Hello,
I have some integer variables, so I almost forced to use GA although I have nonlinear constrains, three objective functions, and many hundreds of variables ...
anyway
I combined the three objective functions in one objective function by multiplying each one by a certain weighting parameter ranging from 0 to 1.0
I built up my code in one .m file (containing the fitness function, the constrain function, and the GA function)
my two questions are:
1- I repeated the problem settings and constants in all these three functions, so my code became long, how can I define them only once ?
2- I wanna know the final value of all the three objective functions as well as some other variables in order to compare results, how can I do that ?

I am not sure if my thread is clear enough,
if you wanna help and couldn't follow my thread, kindly ask me for clarification,
thanks in advance,
Kind Regards
Mamdouh

What is a watch list?

You can think of your watch list as threads that you have bookmarked.

You can add tags, authors, threads, and even search results to your watch list. This way you can easily keep track of topics that you're interested in. To view your watch list, click on the "My Newsreader" link.

To add items to your watch list, click the "add to watch list" link at the bottom of any page.

How do I add an item to my watch list?

Search

To add search criteria to your watch list, search for the desired term in the search box. Click on the "Add this search to my watch list" link on the search results page.

You can also add a tag to your watch list by searching for the tag with the directive "tag:tag_name" where tag_name is the name of the tag you would like to watch.

Author

To add an author to your watch list, go to the author's profile page and click on the "Add this author to my watch list" link at the top of the page. You can also add an author to your watch list by going to a thread that the author has posted to and clicking on the "Add this author to my watch list" link. You will be notified whenever the author makes a post.

Thread

To add a thread to your watch list, go to the thread page and click the "Add this thread to my watch list" link at the top of the page.

What are tags?

A tag is like a keyword or category label associated with each thread. Tags make it easier for you to find threads of interest.

About Newsgroups, Newsreaders, and MATLAB Central

What are newsgroups?

The newsgroups are a worldwide forum that is open to everyone. Newsgroups are used to discuss a huge range of topics, make announcements, and trade files.

Discussions are threaded, or grouped in a way that allows you to read a posted message and all of its replies in chronological order. This makes it easy to follow the thread of the conversation, and to see what’s already been said before you post your own reply or make a new posting.

Newsgroup content is distributed by servers hosted by various organizations on the Internet. Messages are exchanged and managed using open-standard protocols. No single entity “owns” the newsgroups.

There are thousands of newsgroups, each addressing a single topic or area of interest. The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup.

How do I read or post to the newsgroups?

MATLAB Central

You can use the integrated newsreader at the MATLAB Central website to read and post messages in this newsgroup. MATLAB Central is hosted by MathWorks.

Messages posted through the MATLAB Central Newsreader are seen by everyone using the newsgroups, regardless of how they access the newsgroups. There are several advantages to using MATLAB Central.

Use the Email Address of Your Choice
The MATLAB Central Newsreader allows you to define an alternative email address as your posting address, avoiding clutter in your primary mailbox and reducing spam.

Spam Control
Most newsgroup spam is filtered out by the MATLAB Central Newsreader.

Tagging
Messages can be tagged with a relevant label by any signed-in user. Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. You may choose to allow others to view your tags, and you can view or search others’ tags as well as those of the community at large. Tagging provides a way to see both the big trends and the smaller, more obscure ideas and applications.

Watch lists
Setting up watch lists allows you to be notified of updates made to postings selected by author, thread, or any search variable. Your watch list notifications can be sent by email (daily digest or immediate), displayed in My Newsreader, or sent via RSS feed.

Other ways to access the newsgroups

Use a newsreader through your school, employer, or internet service provider

Pay for newsgroup access from a commercial provider

Use Google Groups

Mathforum.org provides a newsreader with access to the comp.soft sys.matlab newsgroup
